我们提出了一种在两个远距离节点之间远程制备任意单光子混合态的技术。这种远程态制备(RSP)是利用一些实验上可用的光学元件和器件在偏振和时间轴自由度(DoF)中实现的超纠缠态。在我们的RSP中,发送者根据她对要传输的期望状态的了解,对她的超纠缠光子执行么正操作。通过执行单光子投射测量和经典通信,目标状态将在远程接收器的量子系统中重建。此外,我们还讨论了部分超纠缠态的RSP问题。我们希望我们的研究能够为长距离量子通信场景的研究铺平道路。
We present a technique for remotely preparing an arbitrary single-photon hybrid state between two distant nodes. This remote state preparation (RSP) is accomplished with a hyper-entangled state in polarization and time-bin degrees of freedom (DoFs) using some experimentally available optical elements and devices. In our RSP, the sender performs unitary operations on her hyper-entangled photon in accordance with her knowledge of the desired state to be transmitted. By performing a single-photon projective measurement and classical communication, the target state will be reconstructed at the remote receiver’s quantum system. Furthermore, we discuss the RSP via a partially hyper-entangled state. We expect our study can pave the way towards the investigation of long-distance quantum communication scenarios.
